Primary Directions Doctrine
Definition
Primary directions are a traditional timing family based on the apparent daily motion of the celestial sphere.
This account describes a constrained geometric implementation and does not claim to cover every historical direction method.
History and sources
The cited sources combines a traditional primary-directions guide with technical astronomy references for the coordinate transformations.
That mix supports calculation language while keeping historical variants separate.
How it is calculated
The method described here uses ecliptic-to-equatorial conversion, ascensional difference, oblique ascension, and same-quadrant semi-arc logic for selected directions.
these methods are treated these as technical preconditions for a narrow lane, not as a complete catalogue of direction keys and promissor-significator policies.
Variants
Primary directions have many historical lanes, including different keys, different promissor sets, and different latitude or quadrant policies.
This overview only describes the method described here named in the cited material.
What this doctrine covers
The cited material covers the narrow semi-arc calculation family and its technical astronomy footing.
It should not promise complete primary-direction judgement or every traditional variant.
Scope and limitations
The cited sources do not establish outcome delineations from directed contacts and does not resolve all historical direction-key controversies.
Those claims need separate cited material with lane-specific locators.
Related practices
Primary directions are part of the broader timing family alongside profections, decennials, firdaria, and return-based revolution work.
